.
as stated both same filters (green cotton)
both cars under 4 month old both from essex ford
both with pirelli p6000 tires on as standard on the zs
an the ford figure is irrelivant to be honest i was just showing a 10 bhp difference in 2 cars
both were identical bar the colour an both was at the same rr day
